The machine chosen to illustrate the present invention is identical in appearance and in many of its structural details to the machine disclosed in co-pending application for Letters Patent of the United States Serial No. 412,464, filed February 2.5, 1954, by Frank R. Werner and Kenneth C. Flint, inventors, now U.S. Patent No. 2,822,874, to which reference may be had for a full disclosure of similar mechanism illustrated in the present application which is not pertinent to the present invention and whichfor that reason will be described only in a general way herein.

Mechanism pertinent to an understanding of the present invention will be described in detail in the ensuing pages.

Machine in general and its supporting framework The framework of the machine comprises main right and left frames 50 and 51 (Fig. 26) and their corresponding auxiliary frames 52 and 53, which are secured, respectively, to the upper ends of their corresponding main frames, said main frames being secured in proper spaced relationship to each other by a machine base 54, to which they are secured, by a back plate 48, secured between said main frames, and by various cross frames, rods, and shafts. The framework also includes right and left totalizer frames 55 and 56 (Fig. 26), secured, respectively, to their corresponding main frames 58 and 51 by various screw studs, rods, and shafts. The framework also includes a receipt roll support plate 57, a detail support plate 58, and a right printer plate 59, all of said plates being connected to the main frame 59 by means of various screw studs, rods, and shafts in the usual manner. Likewise, a receipt hammer support plate 60 is connected in proper spaced relationship to the right auxiliary frame 52 by various screw studs, rods, and shafts. Also, the framework of the machine comprises a left printer plate 61 (Fig. 26) for the slip-printing mechanism, and a left type wheel support plate 62 for the slip-printing mechanism, said plates being secured in proper spaced relationship, respectively, to the main left frame 51 and to the left auxiliary frame 53.

The base 54 is secured inside a shallow oil-drip pan 63, in turn secured to the top surface of a drawer cabinet 64 (Figs. 1 and 26), and the mechanism of the machine is enclosed in a suitable case or cabinet 65, secured to the pan 63.

The keyboard of the machine comprises, in the present instance, four denominational rows of amount keys 66 (Figs. 1 and 2) and a release key 67 for releasing any depressed amount keys, said amount keys being of flexible construction, wherein the depression of a key in a particular denomination, after a key has already been depressed in said denomination, releases the previouslydepressed key, and so on. The keyboard likewise includes four Clerks transaction or control keys 68 for selecting clerks totalizers corresponding to said keys, and for simultaneously initiating machine operation, and includes five Department or Item control keys 69, which control the selection of corresponding totalizers to receive amounts set up on the amount keys 66, said control keys 69 also arranged to initiate machine operation on being depressed, the same as the Clerks keys 68. The keyboard also includes a unit lock lever 70, often referred to as a total control lever, which is movable to various positions to control the functions being performed in the totalizers. The total control lever 70 (Figs. 1 and 2) is provided with a lock 71, the keys of which are generally retained by some person in authority, for locking said total control lever in certain positions and for locking it against movement into certain other positions. The various positions of the total control lever 70 are engraved upon its face, and, when brought into register with an arrow formed in an opening in the keyboard, through which the face of said total control lever is visible, the lever conditionsthe machine for the type of operation indicated by, the engraving.

Reading from top to bottom (Figs. 1 and 2), the engraved positions on the total control lever are as follows: Reset Row 1, in which the totalizers corresponding to the Clerks keys 68 are reset or zeroized; Read Row 1, in which the wheels of said clerks totalizers are sub-totalized, or read; Register, in which the totalizers corresponding both to the Clerks keys 68 and to the Department keys 69 are conditioned for addition; and Locked Register, in which the machine is locked against operation by all keys being locked against depression. Continuing the engraved positions of the total control lever 70, the next positions are Read Row 2, in which the totalizers corresponding to the Department or Item keys 69 are conditioned for a reading, or sub-totaling, operation, and Reset Row 2, in which the totalizers corresponding to the keys 69 are conditioned for resetting, or totalizing, operations. The lock 71 for the total control lever 70 (Fig. 2) is usually provided with two keys, one of which permits the total control lever to be moved to all positions with the exception of Reset Row 1 and Reset Row 2 positions, and the other key, often referred to as a Reset key, permits the total control lever 70 to be moved to all positions including Reset Row 1 and Reset Row 2. With either of the keys mentioned above, the total control lever 70 may be locked in Locked Register position to prevent operation of the machine.

The amount keys 66 (Figs. 1 and 2) and the control keys 68 and 69 are provided with front and back indicators 72, 73, and 74 (only the front indicators being shown here), which are visible through corresponding openings in the cabinet or case 65, said indicators being positionable under the control of the corresponding keys to visibly indicate the amount and the type of machine operation being performed. In read and resetting operations, often referred to as sub-total and total operations, the amount indicators 72 are positioned under control of the wheels of the selected totalizer corresponding to the control keys 68 and 69, in the usual manner.

The amount keys 66 and the control keys 68 and 69 likewise control corresponding type wheels for printing related data upon a detail strip 75 (Fig. 3), upon an issuing receipt '76 (Fig. 1), and upon an insertable duplicate slip 77 (Fig. 4). A portion of the detail strip, containing the latest entries, is visible through a corresponding opening in the cabinet 65, and the receipt 76 is issued through a slot in said cabinet past a tearing blade, which may be used for separating the finished receipt from the web thereof. A table 78 is provided for presenting the insertable slip 77 to the printing mechanism, and said table is provided with an adjustable stop for determining the positioning of the printing on said insertable slip. A small electric light (not shown) is provided for illnm inating the slip table and the slip when necessary, and said light is controlled by a switch 81, conveniently located on the front portion of the cabinet 65. A removable cap 82 provides access to the light, when necessary, for the purpose of replacing the bulb.

In the present arrangement of the machine of this invention, all entries are made upon the detail strip 75. However, it is not possible to issue a receipt and print upon an insertable slip during the same machine operation, and, to properly condition the machine for a slipprinting operation, a slip key 79, located immediately to the right of the Clerks keys 68, is provided and, upon being depressed, renders the receipt issuing and printing mechanism inoperative and simultaneously activates the slip-printing mechanism. A shiftable slide 163 (Figs. 1 and 2), located immediately below the slip key 79, is provided for manually releasing said key or for manually locking said key in depressed position against auto matic release at the end of machine operation, whenever necessary or desirable.

By referring to Fig. 1, it will be seen that the drawer cabinet 64 contains four drawers, 84 to 87 inclusive,

corresponding to the four Clerks keys 68, the opening of which drawers near the end of operation is efiected by the depression of said corresponding Clerks key 68.

The machine is likewise provided with four special counters 88 (Fig. 1), corresponding to the Clerks keys 68, Which count 1 each time a corresponding key is used to initiate a machine operation; five special counters 89, corresponding to the Department keys 69, which likewise count 1 each time the corresponding ones of said keys are used to initiate machine operation; a reset counter 91, which counts 1 each time the total control lever 70 is moved to Reset 1 or Reset 2 position; and an item counter 90, which in multiple-item transactions counts 1 for each item entered in the item totalizer. The item counter is automatically cleared of the items counted in the previous transaction at the beginning of a succeeding machine operation. The special counters 88, 89, 90, and 91 (Fig. 1) are visible through corresponding apertures in an ofiset angular portion of a cabinet front plate 92, secured to the machine framework.

In addition to the nine totalizers corresponding to the control keys 68 and 69, the present machine is provided with an item totalizer for accumulating the amounts of the items as they are listed in the item-entering operations of a multiple-item transaction and for transferring the total amount of said items into the clerks totalizer corresponding to the depressed Clerks key 68 in a final item total operation. An Item Sub-Total key 80, located immediately below the Clerks control keys 68, is provided for reading the amount in the item totalizer any time during a multiple-item transaction.

Each Clerks key 68 (Figs. 1 and 7) is provided with a pin-type cylinder lock 95, controlled by a key formed by a shank portion 94, integral with the tip or finger portion of the corresponding Clerks key. When the key shank 94 is inseited in the lock, the corresponding Clerks key 68 may be depressed, and, when the key shank is removed from said lock, the Clerks key is locked against depression. This provides a safety feature which prevents the intentional or otherwise entering of amounts into the wrong clerks totalizer and further provides means whereby a clerk may lock his key 68 against depression by unauthorized persons if for any reason it is necessary for him to leave his post of duty.

Secured to the top surface of the cabinet 64 (Fig. 1), directly above the clerks drawers 84 to 87 inclusive, is a coin slab 96, for use in making change.

The present application is directed particularly to the slip printing and feeding mechanisms of cash registers and accounting machines, and said mechanisms and all other mechanism closely associated therewith will be described in detail in the ensuing pages. Other mechanism illustrated herein, and not pertinent to the slip printing and feeding mechanisms, will be described only in a general way, and, if a more complete description of said mechanisms is desired, reference may be had to the co-pending United States application Serial No. 412,464, referred to before, and to the co-pending United States application Serial No. 341,633, filed March 11, 1953, by Frank R. Werner, Kenneth C. Flint, and Walter G. Sterzer, inventors, which applications provide a complete disclosure of the mechanisms embodied in machines of this type.

Type wheels and their transmission mechanism for the slip printer As fully disclosed in the co-pending United States application Serial No. 341,633, but not in this application, each denominational row of amount keys 66 (Figs. 1 and 2) has associated therewith a differential mechanism comprising a primary dilferential member, which is positioned under control of the depressed amount key in adding operations and under control of the corresponding wheel of the selected totalizer in reading and resetting operations, in the first instance in accordance with the value of the depressed amount key, and in the second instance in accordance with the value of the amount standing on the corresponding totalizer wheel. After the primary differential member has been positioned as explained above, it is clutched to a corresponding secondary differential member, which has previously been restored to zero position. Return movement of the primary differential member from set position to home, or zero, position causes the corresponding secondary member to be positioned in accordance with the positioning of said primary member. The primary differential members have teeth arranged to be engaged by the teeth of corresponding denominational order wheels of the selected totalizer. In adding operations, the values set up on the amount keys 66 are transmitted to the corresponding Wheels of the selected totalizer, and in sub-total and total operations, often referred to as reading and resetting operations, the primary differential members rotate the corresponding wheels of the selected totalizer to zero position to position said primary members in accordance with the value standing on said totalizer wheels.

The secondary differential member is connected by gearing to a corresponding transmission gear sector, having internal gear teeth which, through a pinion mounted on one of a series of square shafts 97 (Figs. 5 and 15), rotates said shaft in accordance with the positioning of said secondary member under influence of the primary member. Likewise, external teeth on the transmission gear sector engage a pinion connected to the corresponding front and back amount indicator 72, to position said indicators in accordance with the positioning of the secondary member under influence of the amount keys or the selector totalizer Wheel.

The differential mechanism described in a general way immediately above is not disclosed herein, but reference may be had to Fig. 4 of the co-pending application Serial No. 341,633, and the description in connection therewith for a full explanation of this mechanism.

The square transmission shaft 97 (Fig. 5) being described is connected by a small pinion to the internal teeth of a corresponding transmission gear 98, said internal teeth bearing on the periphery of a disk (not shown) in turn supported by a shaft 99 extending between the plate 62 and the left auxiliary frame 53. External teeth on the gear 98 mesh with the teeth of a gear 100 integral with a corresponding slip type wheel 101 rotatably supported on a shaft 102 in turn supported by the plate 62 and the left auxiliary frame 53. There is amount type wheel 101 for each of the four denominational rows of amount keys 66 (Figs. 1 and 2) and for three overflow or higher denominational orders, making a total of seven amount type wheels 181 (see also Fig. 3). The square shaft 97 is connected to transmission gears (not shown), similar to the gear 98, for positioning type wheels (not shown) to print records of the amounts on the detail strip 75' and upon the issuing receipt 76 (Figs. 1 and 4).

The Clerks control keys 68 (Figs. 1, 2, 3 and 4) have associated therewith a differential mechanism (not shown) similar in many respects to the amount differential mechanism, said differential mechanism being connected to corresponding type wheels and indicators for printing clerks identification letters (A to D) immediately to the right of the amounts in item total operations, as shown in Figs. 3 and 4, and for positioning the corresponding indicators 73 (Fig. 1) corresponding to the depressed key 68. The Sub-Total key coacts with the same differential mechanism that the Clerks keys 6S coact with, to cause a sub-total symbol (SUB) (Fig. 4) to be printed opposite the amount, when the item totalizer is sub-totalized. Likewise, the Department control keys 69 have associated therewith a differential mechanism (not shown), similar to the amount differential mechanism, for positioning corresponding type wheels- (not shown) to print an identifying number in Roman numerals, I to V inclusive, opposite the item amounts to show that said amounts were entered in the department or group totalizer corresponding to the depressed control key 69. The symbols for the control keys 69 and the Sub-Total key 80 (Figs. 3 and 4) ar printed only upon the detail strip 75, while the letters for identifying the Clerks keys 68 are printed both upon the detail strip 75 and upon the slip 77, as shown here. The Department control keys 69 likewise control the positioning of the corresponding indicators 74 (Fig. l) to visually indicate the number of the group totalizer corresponding to the depressed control key 69.

In addition to the type wheels referred to above, the slip-printing mechanism includes date wheels for printing the month, the day, and the year upon the slip 77, as shown in Fig. 3. The date-printing wheels are settable by knobs located on the right-hand side of the machine, said knobs also simultaneously positioning the date wheels for printing the date upon the issuing receipt. However, it will be noted that the date is not printed upon the detail strip 75 (Fig. 4). It will likewise be noted that a consecutive number, in this case 1122, is printed both upon the detail strip 75 and upon the insertable slip 77, said consecutive number being utilized to count the transactions as they are being performed by the machine.

Depression of the slip key 79, to initiate a slip-printing operation, controls mechanism which causes a no-receipt symbol, in this case four short dashes in vertical alinement, to be printed to the left of the consecutive number (Fig. 4) upon the detail strip 75, to record the fact that no receipt was issued in this particular transaction. Likewise, the slip key 79 controls mechanism which causes the letter S to be printed between the no-receipt symbol and the consecutive number, upon the detail strip 75 (Fig. 4) to print a record for identifying each slipprinting operation. In this particular case, the slip type wheel line includes a register number (775), which is printed immediately to the left of the date upon the main and duplicate portions of the slip 77 to identify the machine used in this transaction.

The slip type wheels 101 (Fig. 5) overlie the slip table 78, and a stop finger 107, mounted on said slip table 78, is provided for locating the duplicate slip 77 in proper relationship to said slip-printing wheels. The stop finger 107 may be rocked beneath the top surface of the table 78 to an ineffective position, in case it is desired to print records on certain lines of different types of record material, and two guide lines 393 (Fig. 1), en graved in the top of said table 78, are provided for use in locating such record material in relation to the slipprinting mechanism.

Operation of a slip hammer 103 (Fig. 5) causes a platen 104, carried thereby, to carry the slip 77 and an overlying inking ribbon 105 into contact with the slip type wheels 101 to print a record on said material. The inking ribbon 105 is mounted in a ribbon framework 106, which may readily be removed from the machine as a unit in case it is desirable or necessary. A reinking device is employed in connection with the inking ribbon 105 to maintain said ribbon in properly inked condition, said reinking device being similar to that disclosed in the co-pending applications referred to hereinbefore.

Slip hammer mechanism The slip hammer 103 (Figs. 5 and 11) is rotatably supported on a stud 108, extending between the plate 61 and the left side frame 51 (Fig. 26). A stud 110, supported by side members of the hammer 103, freely supports a tapered roller 109, which coacts with angular operating surfaces 111 and 112 forming a V-shaped depression on the upper end of a hammer-operating cam 113 free on a stud 114 extending between the plate 61 and the frame 51. A torsion spring 125 (Fig. 5) urges the hammerv 103 and the roller 109 downwardly to nor-, mally maintain the periphery of said roller in yielding contact with the depression formed by the operating surfaces 111 and 112. Means, presently to be described, is provided for oscillating the cam 113 first in a clockwise direction (Fig. 11), whereupon the surface 111, coacting with the roller 109, imparts clockwise printing movement to the hammer 103, causing said hammer to carry the slip record material and the inking ribbon into engagement with the slip type wheels 101, to record the data set up on said wheels upon the record material. The roller 109 is adjustable longitudinally upon the stud 110, and thus the tapered periphery of said roller 109 provides means for regulating the degree of imprinting force or squeeze imparted to the hammer by the surfaces 111 and 112 to insure the proper quality of imprint upon the slip record material.

The forward end of a cam-operating pitman 115 is pivotally connected to the cam 113 (Fig. 11), while the. enlarged rear end of said pitman has therein an irregular opening 116, which coacts with an operating stud 117 in an upward arm of a lever 118 free on a rod 119 extend ing between the plate 61 and the frame 51. Y-shaped, arms of the lever 118 carry rollers 120 and 121, which coact with the peripheries of companion plate cams 122 and 123 secured on the left-hand end of an auxiliary cam shaft 124, journaled in the frame 51 and the plate 61. The cam shaft 124 is operatively connected to a main cam shaft 233 and is driven one clockwise revolution (Fig. 11) each machine operation, thereby to operate the slip-printing mechanism.

The gearing connecting the cam shafts 124 and 233 (Fig. 5) consists of a gear 225 fast on said shaft 124 and meshing with a gear 226 free on a stud in the plate 61. The gear 226 meshes with a gear 227 fast on a shaft 228 journaled in the frame 51 and the plate 61. Also fast on the shaft 228 is a gear 229 meshing with a gear 230 free on a stud 231 in the frame 51, said gear 230 in turn meshing with a gear 232 fast on the shaft 233. The shaft 233 is journaled in the machine framework and is operatively connected to the operating motor by suitable gearing (not shown) and a clutch device (not shown), the switch for said motor and the clutch device being rendered effective by the control keys 68 and 69. The motor drives the main cam shaft 233 and the auxiliary cam shaft 124 one counter-clockwise revolution (Fig. 5) and one clockwise revolution (Fig. 11) each machine operation, after which the switch and the clutch device are automatically rendered ineffective.

The pitman 115 (Figs. 11 and 12) is pivotally connected by a link 127 to a forwardly-extending arm of a lever 128 free on the stud 108. A spring 129 urges the pitman 115 clockwise and the lever 128 counter-clockwise to normally maintain a stud 130, carried by said lever, in yielding engagement with the hook-shaped upper end of an operating lever 131 free on the rod 119. A downward extension of the lever 131 carries a roller 132, which coacts with the periphery of a plate cam 133, secured on the cam shaft 124.

Operation of the lever 131 (Fig. 12) by the cam 133, according to the time given in space 9 of the time chart (Fig. 21), first in a clockwise direction, frees the lever 128 and the pitman 115 to the action of the spring 129, which rocks said parts counter-clockwise and clockwise, respectively, causing a stud 134 in said lever 128 to sense for the presence of obstructions in its path, to position the control opening 116 in the pitman 115 in relation to the operating stud 117. When all counter-clockwise movement of the lever 128 is obstructed, the pitman 115 is positioned as shown in Fig. 11, where the Widest portion of the opening 116 is opposite the operating stud 117. Consequently, said stud 117 operates idly in said opening 116 when the lever 118 is operated by the cams 122 and 123 according to the time given in space 1 of the chart (Fig. 21), and, as a result, no printing movement is imparted to the hammer 103. When partial movement counter-clockwise of the lever 128 (Figs. 11 and 12) is permitted under influence of the lever 131 and the cam 133, the pitmfn 115 is positioned downwardly or clockwise, so that a rearward step of the opening 116 is in the path of the operating stud 117. Initial movement clockwise of the lever 118 causes the stud 117, in cooperation with the step, to shift the pitman 115 rearwardly to rock the cam 113 clockwise, thereby causing the surface 111, in cooperation with the roller 109, to impart an impression stroke to the hammer 103, to print a record upon the slip record material.

When full movement counter clockwise of the lever 128 (Figs. 11 and 12) is permitted, upon operation of the lever 131 and the cam 133, the pitman 115 is shifted full distance downwardly, under influence of the spring 129, to move the narrow upper portion of the opening 116 therein into coacting alinement with the operating stud 117. Initial movement clockwise of the lever 118 (space 1, Fig. 21) imparts a first impression stroke to the hammer 103, as explained above, to cause the first impression to be made upon the slip record material, and return movement counter-clockwise of said lever 118 causes the stud 117, in cooperation with the forward wall of the narrow portion of the opening 116, to shift the pitman 115 forwardly to rock the cam 113 counter-clockwise beyond its central position, as shown here. Full movement counter-clockwise of the cam 113 causes the surface 112, in cooperation with the roller 109, to impart a second printing stroke to the hammer 103, to print a second, or duplicate, record upon the slip record material, which was line-spaced prior to said second printing stroke. A rearward extension of the lever 118 (Fig. 11) has therein a V-shaped alining notch, which coacts with a stud 135 in the upper arm of a bell crank 136 free on a stud 137 secured in the left frame 51. A spring 138 urges the bell crank 136 counter-clockwise, causing the stud 135, in cooperation With the alining notch, to yieldingly retain the cam lever 118 in its central position, as shown here, so that the stud 117 will not interfere with the shifting of the pitman 115 during positioning thereof by the lever 128, as explained above.

Slip key control of slip hammer An obstructing surface 140 (Fig. 12) on an arm 141, which is operated by the slip key 79 (Figs. 1 and 2), is normally in the path of the stud 134, to obstruct counter-clockwise movement of the lever 128 and thus hold the pitman 115 in ineffective position, as shown in Fig. 11, so that no movement will be imparted to the cam 113 and the printing hammer 103. The arm 141 is free on a shaft 142 journaled in the frame 51 and the plate 61 (Fig. 26). A downward extension of the arm 141 carries a stud 143, which coacts with an extending finger on a crank 144, free on the shaft 142, to form a flexible connection between said arm and said crank. A link 145 (Fig. 12) pivotally connects the crank 144 to a lever 146 free on a shaft 147 journaled in the main frames 50 and '51. A link 148 pivotally connects the lever 146 to a crank 149 secured on the left-hand end of a shaft 150 journaled in the auxiliary frames 52 and 53. Secured on the right-hand end of the shaft 150 is a crank 151 connected by a link 152 to the rear end of a lever 153 free on a stud 139 in the right auxiliary frame 52. The lever 153 carries a stud 154 (Figs. 12 and 17), which engages a slot in a rearward extension of the lower, or stem, portion of the slip key 79, said slip key being depressibly mounted by means of parallel slots therein in cooperation with a shaft 155, supported by the frames 50 and 51, and a stud 156 secured in the plate 58. A spring 157 is tensioned to urge the slip key 79 upwardly to undepressed position. Depression of the slip key 79 (Figs. 1, 2, and 17), against the action of the spring 157, causes a fiat upper surface on a stud 158, carried by said key, to by-pass a latching shoulder on a latch 159 integral with an arm 160 10 free on a stud 161 secured in the plate 58. As the stud 158 by-passes the shoulder on the latch 159, a spring 162 urges the arm 160 and (lid latch clockwise, to move said shoulder into the path of said stud to retain the slip key in depressed position.

The manually-operable slide 163 (Figs. 1 and 17) is provided either for releasing the slip key 79 when depressed, or for securing said key in depressed position against automatic release. The slide 163 is shiftably mounted by means of slots therein, in cooperation with studs 164 and 165 secured in the plate 58 (Fig. 26). Shifting the slide 163 forwardly, or toward the left (Fig. 17), by means of an upwardly-extending finger piece 167, causes a stud 166, carried thereby, in cooperation with an upward extension of the latch 159, to rock said latch and the arm 160 counter-clockwise against the action of the spring 162, to move the latching shoulder on said latch out of the path of the stud 158, to free the slip key 79 for upward movement to undepressed position, under influence of the spring 157. Shifting the slide 163 rearwardly, or toward the right, when the slip key 79 is in depressed position, moves a latching shoulder 168 on said slide above the fiat upper surface of the stud 158 to secure the slip key 79 in depressed position against release by the automatic releasing mechanism, which, through the arm 160, operates the latch 159 in a manner to be explained later.

When the slip key'79 is not depressed, as shown in Figs. 12 and 17, the connections between said key and the crank 144, explained above, retain said crank in the position shown here, and a spring 169 maintains the stud 143 in yielding engagement with the downward extension of said crank 144, to normally maintain the block ing surface 140 in the path of the stud 134. This obstructs counter-clockwise movement of the lever 128 and thus retains the pitman in its ineffective, or upper, position, as shown in Fig. 11, so that no printing movement will be imparted to the cam 113 and the hammer 103, upon operation of the lever 1118. Depression of the slip key, through the train of mechanism shown in Figs. 12 and 17, rocks the crank 144 downwardly, or counterclockwise, said crank, through the stud 143, carrying the arm 141 in unison therewith, against the tension of the spring 169, to move the blocking surface beneath and out of the path of the stud 134, so that the lever 128 is free to be positioned under influence of the cam lever 131, to render the hammer mechanism operative, to selectively make either one or two impression strokes, during a slip-printing operation, under control of the Clerks keys 68 and the total control lever 70 (Figs. 1 and 2), as will be explained presently. Release of the slip key 79, either manually or automatically, near the end of machine operation, permits the train of mechanism shown in Figs. 12 and 17 to restore the crank 144 and the arm 141 clockwise to normal position, in which the blocking surface 140 is in the path of the stud 143, to again render the slip-printing hammer inoperative.

Interlock between machine-releasing mechanism and slip key Mechansm operated by the key lock line or shaft, when the machine is released for operation, locks the slip key against depression when it is in undepressed position, and locks said key against release when it is depressed, until near the end of machine operation.

Depression of one of the control keys 68 or 69 (Figs. 1 and 2) frees a key lock shaft 171 (Figs. 17 and 19), journaled in the machine framework, for initial movement clockwise, which movement operates mechanism which closes the switch to the operating motor and simultaneously operates the clutch mechanism which connects said operating motor to the main cam shaft 233 (Fig. 5) for operation thereby. Fast on the key lock shaft 171 is an arm 172 having a forward extension, which coacts with a stud 173 in the downward arm of a bell crank 174 (Fig. 19) free on a stud 175 secured in the right frame 50. An upward arm of the bell crank 174 carries a stud 176, which engages the bifurcated lower end of a lever 177, carrying a stud 178, which journals in a bushing secured in the detail support plate 58. The rearward arm of the lever 177 is bifurcated to embrace a stud 179 in a forward extension of an arm 180 free on a stud 181 extending between the frame 50 and the plate 58, said stud arranged to support the supply roll for the detail strip. A spring 182 urges the arm 180 and the bell crank 174 counter-clockwise to normally maintain the stud 173 in yielding engagement with the forward extension of the arm 172.

When the machine is at rest, the key lock shaft 171 and the arm 172 are positioned as shown in Fig. 19 and retain the sole of a foot-shaped upward extension 183 of the arm 180 to the right of and out of the path of a stud 184 carried by the arm 160 (Figs. 17 and 19). Clockwise movement of the shaft 171 and the arm 172, upon release of the machine for operation, permits the spring 182 to rock the arm 180 counter-clockwise to move the sole of the foot 183 beneath the stud 184 to obstruct movement of the arm 160 and the latch 159, causing said latch 159, in cooperation with the stud 158, to obstruct depression of the slip key 79 during machine operation, and to obstruct release of said key after it has been depressed during machine operation. Restoring movement counter-clockwise of the shaft 171 and the arm 172, near the end of machine operation, returns the arm 180 clockwise against the action of the spring 182, to move the sole of the foot 183 out of the path of the stud 184, prior to the functioning of the automatic release mechanism, which rocks the latch 159 out of engagement with the stud 158, to free the depressed slip key to the action of the spring 157 (Fig. 17), which restores said key upwardly to undepressed position.

Slip key releasing mechanism Return movement clockwise of the arm 180, as explained above, causes a rearward surface on said arm, in cooperation with a stud 185 in a lever 186 free on a stud 187 secured in the right frame 50, to rock said lever counter-clockwise. The lever 186 carries, in a rearward extension thereof (Figs. 19 and 20), a stud 188, which underlies and coacts with a similar rearward extension of a lever 189, having a slot 190, which pivotally engages the stud 187. The lever 189 also has, in a forward extension thereof, a slot which freely engages the stud 184 in the arm 160. Counter-clockwise movement of the lever 186, upon restoring movement clockwise of the arm 180, rocks the lever 189 counter-clockwise, which movement is imparted by said lever, through the stud 184, to the arm 160 and the latch 159, to rock said parts also counter-clockwise, against the action of the spring 162, to move the latching shoulder on said latch out of the path of the stud 158, to free the slip key 79 for restoring movement upwardly, under influence of the spring 157, near the end of machine operation.

Mechanism under control of the Clerks control keys 68 (Figs. 1 and 2) is provided for rendering the automatic releasing mechanism for the slip key '79 inoperative during the item-entering operations of multiple-item transactions, and during item-sub-total operations, the latter under control of the Sub-Total key 80.

The differential mechanism for the Clerks keys 68 (Figs. 1 and .2) is operatively connected to the central forward one of the square transmission shafts 97 (Fig. 19), said shaft in turn supporting a pinion 193, which meshes with the internal teeth of a gear sector 194. The ends of the internal teeth on the sector 194 cooperate with the periphery of a corresponding disk 195, supported by the shaft 99, to rotatably support said sector 194.

The sector 194 has a cam slot 196 engaged by a roller.

197 in a rearward extension of a lever 198 free on a stud 199 extending between the plates 49 and 58 (Fig.

26 A forward extension of thelever 198 carries a stud 200, which engages a slot in an arm 201 free on a stud 202 secured in the frame 58, A slot in the arm 201 cugages a stud 203 (Figs. 19 and 20) in the rear end of a slide 204 shiftably supported by means of two parallel slots therein, in cooperation with corresponding studs 205 secured in the plate 58. An upward extension of the slide 204 carries a stud 206, which engages a slot in the lever 189, for the purpose of shifting the rear end of said lever in relation to the stud 188.

As previously explained, a multiple-item transaction consists of several item-entering operations and a final item-total operation. In item-entering operations, the Department control keys 69 (Figs. 1 and 2) are used to initiate machine operation and to select corresponding department totalizers for receiving the amounts of the items. In the item-entering operations, therefore, none of the Clerks control keys 68 are used, and consequently the differential mechanism for said keys remains in zero position, as indicated by the zero opposite the dot-anddash line extending through the slot 196 in Fig. 19. This positions the downward, or smaller, circumferential portion of the slot 196 opposite the roller 197, and consequently said roller and the lever 198 are rocked counterclockwise, which in turn rocks the arm 201 clockwise to shift the slide 204 forwardly. The slide 204 then, through the stud 206, carries the lever 189 forwardly in unison therewith, to move the rearward extension of said lever out of the path of the stud 188 (Figs. 19 and 20), and, as a result, operation of the lever 186 by the arm 180, near the end of machine operation, as explained above, imparts no movement to the lever 189. As a result, the latch 159 is not disengaged from the stud 158, and the slip key 79 remains depressed.

As is usual, the items are simultaneously accumulated in an item totalizer as they are entered in the department totalizers. Sometimes it is desirable to take a subtotal or a reading of the accumulated amount of the items, and to do'this, the Item Sub-Total key is used. Depression of the Item Sub-Total key 80 causes the sector 194 (Fig. 19) to be positioned so that the smaller circumferential portion of the cam slot 196 is opposite the roller 197, the same as explained in connection with the zero position of said sector 194, and, as before, the rear end of the lever 189 is moved beyond the stud 188, so that no releasing movement is imparted to the latch 159 at the end of item sub-total operations. As a result, the slip key 79 remains depressed.

The final item total operation of a multiple-item transaction is initiated by depression of one of the Clerks keys 68, which also selects a corresponding clerks totalizer to receive the item total cleared from the item totalizer. Depression of any one of the Clerks keys 68, through the clerks differential mechanism, positions the sector 194 (Fig. 19) so that the larger circumferential portion of the slot 196 is opposite the roller 197, causing said slot, in cooperation with the roller 197, to rock the lever 198 clockwise, to shift the slide 204 and the lever 189 rearwardly to move the rearward extension of said lever into the path of the stud 188. Operation of the arm 180 and the lever 186 near the end of machine operation rocks the lever 189, the arm 160, and the latch 159 counter-clockwise to disengage said latch from the stud 158, to free the slip key 79 for upward restoring movement under influence of the spring 157. Forward movement of the slide 284 (Figs. 19 and 20), as explained in connection with item-entering and item sub-total operations, moves an upward extension 208 thereof beneath the stud 184 to block the counter-clockwise movement of the arm and the latch 159 to insure that the slip key 79 is locked against releasing movement, after the arm has been moved out of the path of said stud 184.

Additional slip key interlocks Mechanism shown in Fig. 17 is provided for preventing releasing movement clockwise of the key lock shaft 171 when the slip key 79 is in a partially-depressed condition. A downward extension of the slip key 79 carries a stud 209, to which is pivotally connected the upper end of a link 210, the lower end of which is pivotally connected to a leg 211 free on a stud 212 secured in the frame 50. As the slip key 79 is being depressed, the link 210 rocks the leg 211 counter-clockwise, causing the sole of a foot 213 of said leg to move into the path of a roller 214, carried by the arm 172, to obstruct clockwise releasing movement of said arm and the key lock shaft 171 until the slip key 79 is fully depressed and the foot 213 is moved beneath and out of the path of said roller 214, as shown in dot-and-dash lines. Thereafter, releasing movement clockwise of the shaft 171 and the arm 172 causes the roller 214 to move over the foot 213 to secure the slip key 79 in depressed position until said key lock shaft is restored counter-clockwise near the end of machine operation.

In slip-printing operations, it is desirable that the receipt-printing mechanism be disabled or rendered inoperative, and the means for accomplishing this result will now be explained. The stud 209 (Fig. 17) in the slip key 79 pivotally supports the upper end of a link 215 pivotally connected at its downward end to an arm 216 free on a stud 217 secured in the right frame 50. Depression of the slip key 79 rocks the arm 216 counterclockwise, as indicated in dot-and-dash lines, to move a blocking surface 218, on a rearward extension thereof, into the path of a stud 219 in a receipt control lever 220, to obstruct counter-clockwise movement of said lever, and thus disable the receipt-printing mechanism, Whenever the slip key 79 is depressed.

The receipt control lever 220 (Fig. 17) is similar to and functions like the corresponding receipt control lever 791, disclosed in Fig. and the description in connection therewith in the co-pending application Serial No. 341,633.

Depression of the slip key 79 (Fig. 17) causes a rearward extension 221 thereof, in cooperation with a stud 222 in an arm 223 free on a receipt on-and-oif shaft 224 journaled in the printer framework, to rock said arm 223 clockwise. A stud 236 connects the arm 223 to a noreceipt symbol type carrier 235, free on the shaft 224, for concert clockwise movement, which moves said type carrier 235 clockwise into printing position to print a symbol consisting of four vertically-alined dashes on the extreme left edge of the detail strip (Fig. 4) to signify that no receipt was issued in this particular operation. Fast on the on-and-off shaft 224 is an arm 237, having pivotally connected thereto the upper end of a link 238, the lower end of which is pivotally connected to a blocking arm 239, free on the stud 217 and arranged to coact with a bent-over ear formed on the upper end of the receipt control lever 220. A torsion spring 240, wound around the on-and-off shaft 224 and connected between the stud 236 and a stud in the arm 237, urges said parts toward each other to normally maintain said stud 236 and a downward extension of said arm 237 in yielding contact with each other, to form a flexible connection between said arm 237, the arm 223, and the symbol type carrier 235. The flexible connection, efiected by the spring 240, permits the arm 223 and the symbol type carrier 235 to move independently of the arm 237, upon depression of the slip key 79, and consequently said arm 237, the link 238, and the blocking arm 239 may remain in ineffective position, as shown here, while the no-receipt symbol type :carrier 235 is moved to printing position independently thereof.

Secured on the right-hand end of the on-and-off shaft 224 (Fig. 17) is a knob (not shown) for operating said shaft, and a spring-actuated mechanism is provided for yieldingly retaining said shaft and the parts secured thereon in either On or Off position. In Fig. 17, the shaft 224 and connected parts are shown in On position. Rotation of the shaft 224 clockwise by means of the on-and-off knob carries the arm 237, the link 238, and the blocking arm 239 clockwise in unison therewith to move said blocking arm 239 into the path of the bentover car on the upper end of the lever 220, to obstruct counter-clockwise movement of said lever and thus render the receipt printing and issuing mechanisms inoperative.

The operation of the slip-printing hammer 103 (Figs. 4 and 11) is further controlled by the Clerks keys 68, the Sub-Total key 80, the Department control keys 69, and the Total Control lever 70. However, as this controlling mechanism also controls the feeding of the slip record material in slip-printing operations, it is believed preferable to first describe the slip-feeding mechanism and then describe the controlling mechanisms, as they relate to both the slip impression mechanism and the slip-feeding mechanism.

Slip-feeding mechanism As previously explained, the two-portion or duplicate slip 77 (Figs. 3, 5 and 14) is presented to the slip-printing mechanism by being placed upon the top of the table 78 and being slid into a throat formed by said table and the ribbon framework 106, and into contact with the stop finger 107, which locates the duplicate slip in proper printing relationship with the type wheels 101. A heavy metal ball 242, freely mounted in a recess in a cross bar 241 of the ribbon framework 106, forms a paper weight, which retains the slip 77 in proper position on the table 78. The slip may be easily pushed beneath the ball- Weight 242 as it is being moved into printing position against the stop finger 107. In addition to the stop finger 107 (Fig. 5), the slip is further located in proper relationship to the type wheels 101 by means of an upwardlyformed edge 244 on the inner portion of the slip table 78. The bar 241 (Figs. 5 and 14) has mounted therein a shaft 245, which rotatably supports properly-spaced apart pressure rollers 243 arranged to coact with corresponding similarly-spaced feed rollers 246 and 247 secured on a shaft 248, rotatably supported by parallel arms 249 and 250, of similar outline, secured on a shaft 251 journaled in the frame 51 and the plate 61 (Fig. 26). The feed rollers 246 and 247 are arranged to move upwardly through clearance openings in the table 78, into engagement with the corresponding pressure rollers 243, upon operation of the slip-feeding mechanism, as will be explained presently. Also secured on the shaft 251 is a crank 252, pivotally connected by a link 253 to a cam lever 254 free on the rod 119 and carrying a roller 255, which coacts with the periphery of a plate cam 256 secured on the auxiliary cam shaft 124. A spring 257 urges the crank 252, the shaft 251, and the arms 249 and 250 counter-clockwise (Fig. 14), and, through the link 253, urges the lever 254 clockwise to maintain the roller 255 in yielding contact with the periphery of the cam 256.

Operation of the cam 256 according to the time given in space 6 of the time chart (Fig. 21) permits the spring 257 to carry the feed rollers 246 and 247 upwardly to yieldingly carry the slip 77 into contact with the pressure rollers 243, after which rotational movement is imparted to said feed rollers 246 and 247 to feed the slip, as will be explained presently. The shaft 248 (Fig. 14) has secured thereon a gear 258 meshing with a companion gear 259 fast on a shaft 260 journaled between the arms 249 and 250. Also secured on the shaft 260 is a pinion 2611, (Figs. 5 and 14) which meshes with a toothed rack 262 secured to the inner face of a slide 263 shiftably supported by means of slots 264 and 265 therein, in cooperation, respectively, with a bushing mounted on the shaft 251, and with the shaft 260. A link 266 pivotally connects the slide 263 to an operating lever 267 free on the rod 119, said lever having a forward extension with a slot which engages a stud 268 in one arm of a Y-shaped lever 269 free on the stud 114. Another arm of the lever 269 carries a roller270, which cooperates with the periphery of a plate cam 271 secured on the auxiliary cam shaft 124. A spring 272, tensioned between a rearward extension of the lever 267 and a fixed stud (not shown), urges said lever 267 clockwise and the companion lever 269 counter-clockwise to normally maintain the roller 270 in yielding contact with the periphery of the cam 271. As previously explained, the auxiliary cam shaft 124 makes one clockwise revolution each machine operation (Fig. 14) and during this revoluation operates according to the time given in space 2 of the time chart (Fig. 21) to shift the slide 263 first rearwardly, or in a back up direction, and then forwardly in a feeding direction, to feed the slip 77 in a forward direction.

By controlling the extent of initial movement clockwise of the lever 267 (Fig. 14), the degree of feed imparted to the slip 77 upon forward or return movement of said lever 267 may be regulated accordingly. The maximum take-up movement clockwise of the lever 267 may be regulated by means of a stud 2'74 carried thereby, in cooperation with the eccentric periphery of an adjustable stop plate 275 pivoted on the shaft 142 and having a concentric slot, which, in cooperation with a screw threaded in the plate 61, provides means for adjusting the eccentric periphery of said plate in relation to the stud 274, to limit the take-up movement clockwise of said lever 267.

The stud 274 (Figs. 5, and 14) extends through the lever 267 and coacts with a control surface 276 on a segment 278 removably attached to a plate 279 in turn secured to the shaft 142. Likewise, the stud 134 in the hammer control lever 128 (Figs. 9 and 11) coacts with a control surface 280 on a segment 281, also removably attached to a plate 282, in turn secured on the shaft 142. The segments 278 and 281 are positioned under control of the Clerks control keys 68 (Figs. 1 and 2), and positioning of said segments is effected by mechanism including a ratchet segment 283 (Fig. 8) secured on the shaft 142 and pivotally connected by a link 284 to a crank 285 secured on the left end of a shaft 286 journaled in the machine framework.

Secured near the right-hand end of the shaft 286 (Figs. 6 and 8) is an arm 287 carrying a roller 288 normally maintained in yielding contact with a vertical'surface 289 on a slide 290 by a spring 291 tensioned between said arm and said slide. The slide 290 is mounted for horizontal shifting movement by means of a slot near its rear end, in cooperation with a stud 292 secured in the frame 50, and by means of another slot in cooperation with a stud 293 extending between the frames 50 and 55 (Fig. 26). The forward end of the slide 290 (Fig. 6) has a slot which engages a stud 294 fast in the upper end of a crank 295 integral with a lever 296 free on a stud 297 secured in the right frame 50. A spring 298, tensioned between the stud 294 and a stud in the slide 290, forms a flexible connection between said arm and said slide and normally maintains said stud 294 in resilient contact with the rear end of the slot in said slide 290. A spring 299 urges the lever 296 clockwise (Fig. 6) to maintain a roller 300, carried thereby, in yielding contact with the periphery of a cam 301 free on a stud 302 secured in the right frame 50. Integral with the cam 301 is a gear (not shown) which meshes with another gear (not shown) secured on the main cam shaft 233, and operation of said cam shaft drives the cam 301 one counter-clockwise revolution (Fig. 6) each machine operation to operate the lever 296 and connected parts; Secured in the upper end of the lever 296 (Fig. 6) is a stud 304, which engages a slot in a disk 305 free on the stud 217. Secured to the disk 305 is an arm 306 having an upper extension 307 arranged to engage a stud 308 in each of the Clerks keys 68, and in the Sub-Total key 80, to position said disk 305 in accordance with the efiective control keys 68 or 80. In operations in which no control key 68 or 80 is depressed, for example, Item Total operations, an obstruction 309 (Fig. 6), midway between the E key 68 and the Sub-Total key 80, is in the path of the extension 307 of the arm 306 and positions said arm and the disk 305 accordingly. Depression of the Sub-Total key 80 moves the obstruction 309 out of the path of the extension 307 and moves the stud 308 in said Sub-Total key into the path of said extension to cause the arm 306 and the disk 305 to be positioned accordingly. The mutilated periphery of the disk 305, in cooperation with the bentover ear of the receipt control lever 220, controls the operation of the receipt mechanism in accordance with the positioning of said disk under control of the keys 68 and 80. A high portion of the control surface on the disk 305 obstructs counter-clockwise movement of the lever 220 and thus prevents operation of the receipt mechanism, whereas a medium undercut portion of said periphery permits partial movement of the lever 220 to in turn efiect a short feed of the receipt material, and a full undercut portion of the control surface on the disk 305 permits full counter-clockwise movement of the lever 220, to cause the receipt material to be given a long feeding movement, which is desirable, for example, in the item total operation of a multiple-item transaction. The control of the receipt mechanism by the disk 305 is fully disclosed in the application Serial No. 341,633, referred to repeatedly herein.

Positioning of the arm 306 (Fig. 6) and the disk 305, as explained above, is transmitted through the lever 296, the crank 295, and the slide 290 to the arm 287 and the shaft 286. The positioning of the shaft 286 is transmitted by the crank 285 (Fig. 8) and the link 284 to the segment 283, to position said segment in accordance with the positioning of the arm 306 and the disk 305 under control of the Clerks keys 68 and the Sub-Total key 80. The segment 283 (Fig. 8) has, on its periphery, teeth 310, corresponding to the different Clerks keys 68, the Sub-Total key 80, and the obstruction 309, which ratchet over a tooth 311 protruding from a lever 312 free on the stud 137, said lever being urged clockwise by a spring 313 to normally maintain said tooth 311 in yielding engagement with the ratchet teeth 310. The lever 312 and the tooth 311 form a pawl for coacting with the teeth 310 to hold the segment and connected parts in set position. The upper end of the lever 312 (Figs. 8 and 16) underlies a stud 314 in the upper end of a lever 315 free on the rod 119, said lever carrying a roller 316, which coacts with the periphery of a plate cam 317 secured on the auxiliary cam shaft 124.

The earn 317 operates according to the time given in space 5 of the time chart (Fig. 21) to rock the lever 315 first counter-clockwise (Fig. 16) and then back to normal position. Counter-clockwise movement of the lever 315, near the beginning of machine operation, through the stud 314, rocks the ratchet lever 312 also counter-clockwise to disengage the tooth 311 from the ratchet teeth 310 of the segment 283, to free said segment, the shaft 286, and the arm 287 to the action of the spring 291 (Fig. 6), which immediately moves said arm 286 and connected parts counter-clockwise until the roller 288 contacts the surface 289. Immediately thereafter, the cam 301 frees the lever 296 and the slide 290 for positioning movement under urgency of the spring 299, said slide in turn, through the roller 288, positioning the arm 287, the shaft 286, the segment 283, and connected parts in accordance with the positioning of the arm 306, the disk 305 and the lever 296, under control of the Clerks key 68 or the Sub-Total key 80, as explained before. After the segment 283, the shaft 142, and the control segments 278 and 281 (Figs. 9 and 10) have been positioned, the cam 317 (Fig. 16) permits the spring 313 to restore the lever 312 clockwise until the tooth 311 engages the tooth 310, corresponding to the position of said segment 283, to retain said segment in set position, after the slide 290 (Fig. 6) has been restored forwardly under the influence of the cam 301 near the end of machine operation. This permits the segment 283, the shaft 17 l42, and the segments 278 and 281 to remain in set position after the slide 290 has been restored forwardly, so that the parts controlled by said segments 278 and 281 will function properly. Positioning of the arm 306 and connected parts, including the segments 278 and 281 (Figs. 6, 8, 9 and 10), under control of the four Clerks keys 68, locates low surfaces 319 and 320 of said segments 278 and 281 opposite the studs 274and 134, respectively, for the slip feed control lever 267 and the slip hammer control lever 128, to permit full movement of said levers 267 and 128, unless they are otherwise controlled, to cause said levers in turn to permit full feeding movement to be imparted to the slip 77 (Fig. 14) and to permit two impression strokes to be imparted to the hammer 103 (Fig. 11) in the manner previously explained. Positioning of the segments 278 and 281, under control of the Sub-Total key 80 or under control of the obstruction 309, which, as previously explained, is effective when no key 68 or 80 is depressed, causes the high surfaces 276 and 280 of said segments to be moved opposite the respective studs 274 and 134 to obstruct movement of the levers 267 and 128 to prevent feeding movement from being imparted to the slip 77 and to prevent operation of the slip hammer 103.

Obviously the control surfaces on the segments 278 and 281 (Figs. 9 and 10) may be arrangedin any desired manner to obtain the required control of the slip-feeding and hammer mechanisms. For example, an intermediate surface 321, shown in Fig. 9 in dot-and-dash lines, may be provided on the segment 281 for coacting with the stud 134, when said surface is positioned opposite said stud 134, under control of the D or E Clerks keys 68, to cause one impression stroke to be imparted to the hammer 103. Likewise, the segment 278 may be altered in a similar manner to control the extent of clockwise movement of the lever 267 (Fig. 10) to cause a short feed of the slip record material when the segment 278 is positioned under control of the D or E Clerks keys 68.

The slide 290 (Fig. 6) also controls the positioning of a consecutive number operating pitman 322, to determine when the units wheel of the consecutive number type wheels will be advanced one digit to keep an accurate count of certain transactions performed by the machine. The rearward portion of the slide 290 has a substantially vertical slot engaged by a stud 318 in the pitman 322, said pitman being pivotally connected to an arm 323 pivoted on a stud 336 in the frame 50 The arm 323 carries at its forward end a stud 324, which engages a cam slot in a consecutive number operating arm 325 operatively connected to the tined feed pawl (not shown) which actuates the consecutive number type wheels. An enlarged downward extension of the pitman 322 has an L-shaped slot 327 (Fig. 6) engaged by a stud 328 in an operating lever 329 free on a stud 330 in the frame 50. A forward extension of the lever 329 has a stud 331, which engages a slot in a rearward extension of a lever 332, in turn rotatable on a shaft 333 supported bythe machine framework. Camming surfaces, formed on forward extensions of the lever 332, coact'with a stud 334, carried by a disk 335, in turn secured upon the main cam shaft 233. A spring 326 urges the levers 329 and 332 counter-clockwise and clockwise, respectively, to maintain the camming surface on the lower extension of the lever 332 in yielding engagement with the stud 334, as shown here (Fig. 6). The Clerks keys 68, through the arm 306, the disk 305, and connected parts, cause the slide 290 to position the pitman 322 so that the substantially horizontal branch of the slot 327 is in coacting relationship with the stud 328, and, consequently, clockwise rotation of the shaft 233 and the disk 335 causes the stud 334 to first rock the levers 332 and 329 clockwise and counter-clockwise, respectively, to shift the pitman 322 upwardly to rock the arm 323 clockwise. Clockwise movement of the arm 323 (Fig. 6) causes the stud 324, coacting with the slot in the arm 325, to impart back-up, or retrograde, movement to the feed pawl for the consecutive number type wheels. Continued rotation of the disk 335 and the stud 334 causes said stud to restore the levers 332 and 329 counter-clockwise and clockwise, respectively, to shift the pitman 322 downwardly. Downward movement of the pitman 322 returns the arm 323 counter-clockwise to operate the consecutive number feed pawl in a feeding direction to advance the units consecutive number type wheel one digit, so that a consecutive number for identifying the transaction will be printed upon the detail strip 75 and the insertable slip 77 (Figs. 3 and 4).

Depression of the Sub-Total key 80 causes the slide 290 (Fig. 6) to position the pitman 322 so that the substantially vertical branch of the slot 327 is opposite the stud 328, and, as a result, said stud operates idly in said vertical branch and therefore does not impart any feeding movement to the pitman 322, so that the consecutive number type wheels will not be advanced in item subtotal operations. Likewise, when neither a Clerks key 68 nor the sub-total key 80 is depressed, the obstruction 309 (Fig. 6) is effective to control positioning of the slide 290 and in turn causes said slide to position the pitman 322 so that the substantially vertical branch of the slot 327 is opposite the stud 328, and under such conditions no feeding movement is imparted to the consecutive number type wheels. The consecutive number mechanism shown in Fig. 6 is similar in every respect to that disclosed in Fig. 40 and the description in connection therewith in the co-pending application Serial No. 341,633, to which reference may be had for a more complete explanation of said mechanism.

Total lever control of slip feeding and impression mechanisms In addition to the control of the slip-feeding and slip impression mechanisms by the first row of control keys 68 and 80, the total control lever 70 (Figs. 1 and 2) likewise actuates mechanism which exercises an additional control over these mechanisms.

The total control lever 70 (Figs. 1, 2 and 18) is rotatably supported on a shaft 338 journaled in the machine framework, said shaft being the supporting shaft for the diiferential mechanism for the amount and the control banks. A slot in the upper portion of the lever 70 engages a stud 339 fast in the downward end of an arm 340 secured on a shaft 341 journaled in the machine framework. Also secured on the shaft 341 (Figs. 13 and 18) is a downwardly-extending arm 342, having a hole which freely engages a tenon formed on a stud 343 secured near the downward end of an arm 344 journaled on a trunnion stud 345 secured to the outer face of the left frame 51, in axial alinement with the shaft 341. The arm 342 is on the right side of the left frame 51, and the arm 344 is on the left side of said frame, so that it is necessary to provide a clearance hole (not shown) in said frame for the stud 343, so that the arms 342 and 344 are free to operate in unison. The arm 344 (Fig. .13) is pivotally connected by a link 346 to a slip hammer control plate 347 secured to a sleeve 348 free on the shaft 142, said sleeve also having secured thereto a slip feed control segment 349.

The control surface or periphery of the plate 347 cooperates with the stud 134 in the hammer control lever 128 (Figs. 11 and 13), and, when the total control slide 70 (Fig. 18) is in Register position, as shown here, a low or notched portion of the periphery of said plate 347 is opposite the stud 134, and consequently does not interfere with counter-clockwise movement of the lever 128. Therefore said lever is free to be controlled in other ways; for example, by means of the segment 281, shown in Fig. 9. Moving the total control lever 70 to any position, other than Register position, moves a high portion of the periphery of the control
